摘要

An object of the present invention is to provide a die silent gujoeul of the drawing die of the blank holder in the drawing die as small as possible can reduce the noise generated in the contact with the thin plate on the. Silent structure of the drawing die contains a punch, is fitted to the punch circumference as possible the vertical movement disposed so as to face the blank holder and punch movably supported vertically by a cushion pin punch thin plate is moved up by the cushion pin to be placed on the blank holder is die to the drawing by a thin plate is lowered to the punch die and the blank Roasting insert the lamina lower die base plate between the holder blank holder so that the blank holder rises before the die impinges on the lamella to have a run-up lever rotatably for pressing and operating cam for driving the run-up lever is disposed at a position over the run-up lever toward and die impinges on the thin plate on the blank holder after rising the blank holder.
